Exponential Function by. Maxx Kim

pg. 88
FX- 60 a) f(x)= 3x^2
This is not a exponential function because there is a ^2 instead of ^x. All exponential functions look the similar on a graph. Below is what a) looks like. As you can see its a parabola.



b) h(x)= (3)^x
This is a exponential function because the exponent is x. As long as it has the x as a exponent it is a exponential function. My proof that it is a exponential function is because of the graph.




Every exponential Function will be graphed like this.

Another example, c)
y=5(4)^x
again this is another exponential function because it has the x as a exponent. This graphed looks like this.

again the graph looks the same at b)

One more example, d)
g(x)=(2.46) ^x
Again this is a exponential function because it has the x as an exponent. This is what the graph looks like. Again you will see that it is similar.
